To all whom it may, concern:

Be it known that'I, OsoAR BERNHEIMER, subject of the Emperor of Austria-Hungary, residing at Vienna, Austria-Hungary, have invented certain new and useful Improvements in Disinfecting Compositions, of which the following is a specification.

The present invention has for its object to provide animproved, efficient and relatively inexpen'sive-mibrobieide or disinfecting agent and also a process of producing thesame, the character of the microbicide being such that it can be prepared and used conveniently and will act quickly and with certainty in destroying fungi, bacteria, pathogenic and other microbicide organisms, it consisting of a compoundof bisulfate of soda and sodium borofluorid, the compound possessing greater antiseptic properties than those of corresponding quantities of the two ingredients when used separately.

The following is given as an example of a. microbieide prepared in accordance with the present invention: Iflqui-moleeular quantities of sodium borofluorid and bisulfate of soda, that isto say, 110 parts per weight of the first named combination per weight of the latter combination are mixed in a dry'condition and an aqueous solution of this mixture is prepared of a degree of concentration which may vary ac cording crobicidal agent is to be used.

In using-a microbicide produced ,in accordance with the present invention the aqueous solution may be applied for instance in. places Where fermentation takes place. For example, it may be used for the purpose of washing out and rinsing vats, tuns or wooden cisterns, store casks or vats, tubes or hose, beer conduits and, in fact, it may be used for cleansing apparatus of various kinds. The microbicide, moreover, may he used for washing filtering masses, as a. coaling for the walls of working rooms, for washing floors or for disinfecting" drains and conduits of various ,kii (ls.

from pathogenic germs, the microbicide may be prepared as above described and applied in the usual manner, the mierobicide in the form of an aqueous solution being used for washing and rinsing the objects and surfaces that are to be disinfected. The microbicide is particularly adapted for use as a disinfectant for clothes during Washing may be kept in the solution.'

The degree of concentration ofthe solution' Will vary according to the particular uses to which it is to be applied. For most purposes a solution of'from one to two per cent. will be suflicient, while in those cases where the microbicide is to be used, for instance as a disinfecting coating for the walls of establishments where fermentation takes place, it may be best to employ a solution of about ten per cent. I.

Practice has demonstrated that a microbicide composed of a compound of bisulfate of soda and sodium borofluorid possesses greaterantiseptic or microbicidal properties than corresponding quantites of bisulfate of soda and sodium borotluorid when used separately. The increased efliciency of the compound of these two ingredients seems to be due to a chemical reaction whi' h occurs from the mixing of the ingredients and is due to the formation of salts of complex acids containing fluorin or boron and fluorin, as experiments would indicate that no combinations of boron or fluorin escape even when the solution is evaporated in a water-bath to the consistency of thick syrup.

a I claim as my invention:

A microbicide composed of hisulfate of vsoda and sodium horoliuorid.

In testin'iony whereof I have hereunto set my hand In n'escuce of two subscribing Witncsscs.
